This is 19-year-old Matthew Selby pictured with his arm around his younger sister Amanda, whom he is accused of taking on a family holiday to a busy seaside caravan site.
North Wales Police have described the tragedy as a ‘domestic disturbance’ at Ty Mawr Holiday Park near Rhyl.
Selby is suspected of murdering his younger brother Amanda, assaulting and seriously injuring their father, and then holding their grandfather hostage before his arrest on Saturday.
District Judge Gwyn Jones of the Magistrates Court of Llandudno has him in custody until tomorrow at Mold Crown Court.
Dressed in a gray sweatshirt and between two guards in the glass dock, Selby spoke only to confirm his name, address and date of birth and to confirm that he understood the charges.
Prosecutor James Neary said there was no right to bail, while Selby’s attorney Simon Sargent said in a hearing that lasted less than two minutes: “I have nothing to add, except to say that this is a tragic case.”
An air ambulance arrived at the scene on Saturday afternoon, as parts of the Parkdean resort and a caravan were cordoned off as police investigated the 100-acre park.

An air ambulance rushed to the scene on Saturday afternoon at Ty Mawr Park in Towyn, North Wales
Eyewitnesses reported that the air ambulance landed around 3.30pm on the A548, which was closed in both directions, with two ambulances and three fast-responding vehicles in tow.
A police spokesman said: ‘Following an incident at Ty Mawr Holiday Park, Towyn, on Saturday afternoon, 19-year-old Matthew Selby from the Greater Manchester area has been charged this afternoon with murder’.
Mother of two Carly Hargreaves, 44, who arrived on holiday from Manchester on Friday, said about eight police cars, three ambulances and the trauma helicopter arrived at the park.
She said from outside the huge caravan and campsite: ‘We are two rows behind where it happened and have heard nothing.
“I just have to think about it because my son is 16. Going on vacation and not going home with that special someone is tragic. It’s a normal family-oriented site.’
On Sunday, police cars were seen driving into the site as the investigation continued.
Close to the sea and part of the Parkdean Resorts chain, Ty Mawr is one of the more upscale vacation spots, including a heated indoor pool, far from the raw and ready-made image of camps of yesteryear.
Tens of thousands of holidaymakers stay in camps along a stretch of coastline during what is traditionally one of the busiest weeks of the year.
Police were called to a ‘serious incident’ at a holiday park in Wales and warned people to ‘stay away’ after the ‘tragic incident’
Police said: “We would like to ask the public not to speculate about this incident on social media as this is an active investigation.”
Footage of the scene posted on Saturday showed dozens of people waiting in a parking lot while an air ambulance and police cars were parked nearby.
Another image showed a caravan that had been taped up by detectives.
Kay Redhead, Mayor of Towyn and KInmel Bay said, “It has touched us deeply. This is a fantastic place where we welcome everyone. This time of year we have 45,000 to 50,000 extra people around and with staycation it’s all buzzing. Ty Mawr is a well organized and run family camp and when something like this happens it affects everyone.”
Ms Redhead added: ‘I would like to extend my condolences to the family. It’s a tragic situation.’
A spokesperson for Ty Mawr holiday park, which is part of the Parkdean Resorts brand, said over the weekend he was “shocked and saddened” by the incident, describing it as “isolated and unprecedented.”
